Given numbers are 490,227,716,91

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 490,227,716,91 is 517664420.

Find LCM of 490,227,716,91 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 7 x 35 x 227 x 358 x 13 = 517664420

Therefore, the lowest common multiple of 490,227,716,91 is 517664420.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

490 x 227 x 716 x 91 = 7247301880

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

227 : 1, 227

716 : 1, 2, 4, 179, 358, 716

91 : 1, 7, 13, 91

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 490,227,716,91, is 1.

Now, the common factors can be found like this.

490:2x 5x 7x 7

227:227

716:2x 2x 179

91:7x 13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 7 = 14

Therefore, the value for common factors is 14.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 7247301880/(1x14)

LCM = 7247301880/14

LCM = 517664420

Thus, we can understand that the LCM of 490,227,716,91 is 517664420.
